This study used a combination of photocatalytic oxidation (PCO) reaction and electromagnetic field for benzene (486 ÃÂ± 129.07 ppb) or toluene (704 ÃÂ± 77.00 ppb) degradation in air. To develop surface morphology and PCO reaction, the application of a polymer (polyethylene glycol 4000; PEG 4000) support for nano-dispersed commercial P25 TiO2 on a high efficiency particulate air (HEPA) filter was investigated for the effect of varying baking temperatures, i.e. below and above melting point (50 and 100°C, respectively) of the PEG 4000. The HEPA filters were dip-coated with different amounts of the TiO2 and PEG 4000 and their...
